Haha, I'm not entirely sure without a name, and I was busy with something else when the director was going over the dance list with the cast, but... I can say that we have a mix of songs and many of the cast members have some ballroom dance training so they can lead to the variety of songs played. I know for a fact director-man has a soft spot for swing. XD
There are always a couple of party songs played as well, the ones that have giant dance numbers that lots of people know and can teach, like Cupid Shuffle or Electric Slide.
